Hi,
I'm trying to remotely upgrade my server from
gentoo-sources-2.4.25_pre7-r2 to gentoo-sources-2.6.13-r9, i.e. from
devfs to udev. My root partition is on a RAID 1 mirror on an Adaptec
2100S. My existing fstab is below. It was summarized to me by the
NOC over the phone, so I don't have the exact text of the startup
error, but it is something to the effect of...
/dev/scsi/host0/bus0/target0/lun0/part3 not found
I'm guessing that udev is tweaking the naming scheme a bit, as warned
under "No Consistent Naming between DevFS and udev" in the Gentoo udev
Guide.
So two questions:
1) How can I tell what the new name is going to be?
2) As I'm doing this upgrade remotely, how can I set up to fail back
to my udev-less 2.4.25 kernel should 2.6.13 still fail to come up? In
other words, if I change fstab to be udev specific won't that leave me
dead in the water?
Thanks!
Ian

# Adding the following line to /etc/fstab should take care of this:
